Spår av tillverkningsmetoder i glas : En studie av redskapsspår i glas från BirkaRåhlander, Moa January 2015 (has links)
This is an experimental study of a few glass objects from the Birka Excavations 1987-1989. A number of beads and waste from bead production have been studied. A group of these objects have also been examined with a scanning electron microscope (SEM) equipped with energy-dispersive detectors (EDS) to comparatively analyze the materials composition. Experiments to recreate the technique in which they were made have been attempted with various results. The techniques found in the beads include the use of murrini, stringer, dotting, and blown-drawn. However the waste material available to this study only suggests that in Birka, beads where made with the winding technique and ornamented with stringer and possibly dotting. The glass used was heated in clay crucibles and some rods where premade.
